Racial discrimination is when someone is discriminated on the basis of their race. It doesn't matter how friendly the perpetrator is to people of other races.
a) disliking all races different from one's own b) using one's life experience to form opinions about people and grouping them by - age / race / occupation / ethnicity / etc.
I think that using same word is wrong - as they are completely different phenomena.
Basically, the general definition of racism is more about prejudice against one or more races, rather than about uplifting one specific race above everything else.
